Drawing the Line: Post-CIRP Tax Dues and the Limits of the Clean Slate Doctrine
Manish Sachdeva
1. Introduction
The Insolvency and Bankruptcy Code, 2016 ("IBC") was designed to breathe new life into financially distressed enterprises by enabling a clean, time-bound resolution process. Central to this design is the "clean slate doctrine", the principle that a successful resolution applicant ("SRA") takes over the corporate debtor ("CD") free from the weight of undisclosed or unresolved historical claims. For years, this doctrine was understood by many practitioners as conferring comprehensive immunity from all dues not addressed in the approved resolution plan, including statutory dues owed to government authorities. Two recent judgments of the Madras High Court, P Dot G Constructions Pvt. Ltd. vs ACIT (2026-VIL-80-MAD-DT) and Aqua Terra Coke and Energy Ltd. vs ITO (2026-VIL-95-MAD-DT), have decisively narrowed this understanding. Both hold that the clean slate doctrine does not extinguish tax dues arising during the Corporate Insolvency Resolution Process ("CIRP") phase, resolving a long-standing ambiguity in the cross-section of the IBC and tax laws. This article examines the nuances of the judgments and their aftermath.
2. The Clean Slate Doctrine: Contours and Relevance
The clean slate doctrine finds its statutory foundation in Section 31(1) of the IBC, which provides that an approved resolution plan shall be binding on the CD, its employees, members, creditors, including the Central Government, State Governments, and all authorities to whom statutory dues are owed — and all other stakeholders. The Supreme Court gave authoritative shape to the doctrine in Essar Steel India Ltd. (2020) 8 SCC 531, holding that an SRA cannot be "suddenly confronted with undecided claims". This was affirmed and expanded in Ghanashyam Mishra - 2021-VIL-55-SC, where it was held that all claims not forming part of the approved resolution plan stand extinguished on the date of approval. However, the fate of post-moratorium dues remained unresolved. The two Madras High Court judgments now answer that question in the negative, and the reasoning merits careful examination.
3. The Judgments in P Dot G and Aqua Terra
3.1 P Dot G Constructions
CIRP against P Dot G Constructions was initiated on 13 July 2018. The assessment year in dispute was 2018-19, relating to income earned during the financial year ending 31 March 2018, a period that partially overlapped with the CIRP. Crucially, the due date for filing the return of income for this assessment year fell on 31 October 2018, well after the CIRP had commenced, and the RP failed to file it. A resolution plan was approved by the NCLT on 13 December 2019. The SRA subsequently challenged reassessment proceedings, claiming immunity under the clean slate principle.
The Madras High Court rejected this claim, noting that the NCLT itself, while approving the plan, had expressly declined to sanction the blanket tax extinguishment clauses sought by the SRA. Further, the resolution plan contained the SRA's own undertaking to file pending returns and work out tax liabilities. The Court held that aforesaid clean slate precedents Essar Steel and Ghanashyam Mishra concerned pre-CIRP dues on their facts and could not be extended to liabilities arising during the CIRP period.
3.2 Aqua Terra: Facts and Holding
Aqua Terra was a consolidation of seventeen writ petitions spanning GST and income tax disputes across multiple CDs that had undergone CIRP or liquidation. The central question was common: does the clean slate doctrine extinguish fiscal dues arising during the CIRP period, specifically, GST demands under Sections 73/ 74 of the Tamil Nadu GST Act and income tax reassessments under Section 148A of the Income Tax Act for assessment years falling within the CIRP window. The Court conducted a comprehensive examination and answered the question firmly in the negative. Broadly four thematic pillars of the Court’s reasoning merits discussion;
Pillar 1 - Precedential Limitation and Purposive Restraint:
The Court deployed both procedural and purposive reasoning to contain the clean slate precedents. On the procedural plane, it applied the settled rule that a judgment is authority for what it actually decides, not what logically follows from it. Since Essar Steel, Ghanashyam Mishra, and others all arose in the context of pre-CIRP dues, their ratio is not a binding precedent apropos post-CIRP dues. The Court also invoked the sub silentio doctrine, since the question of post-CIRP dues was never "present to the mind" of the Supreme Court in those cases. On the purposive plane, the Court held that the clean slate doctrine is designed to ensure that the "problems of the earlier regime" do not travel into the revived entity. Post-CIRP tax obligations, arising from transactions conducted by the RP in managing the CD, are manifestly not the baggage of the erstwhile management, they are costs incurred in the course of the resolution process itself.
Pillar 2 — The Structural Architecture of the IBC:
The IBC draws a structural distinction between "claims", being rights to payment existing as on the insolvency commencement date and "Insolvency Resolution Process Costs" ("IRPC"). Post-CIRP tax dues, GST, TDS, income tax, are not "claims" in the IBC sense, they cannot be lodged before the RP because they had not arisen at the time of claim collation. The clean slate, as a legal mechanism, operates exclusively on the domain of claims. It cannot extinguish what structurally falls outside that domain. This reasoning is reinforced by Section 30(2)(a), which mandates that every resolution plan shall provide for payment of IRPC in priority. A plan that purports to extinguish post-CIRP tax dues, would violate this mandatory provision and could not receive the RP's certification under Section 30 (2) (e).
Pillar 3 — Internal Statutory Mandates for CIRP-Period Compliance
The Court drew on several provisions within the IBC itself to demonstrate that the statute contemplates continued fiscal compliance during the moratorium, including Section 17 (2) (e) expressly requires the IRP/RP to comply with "requirements under any law for the time being in force" on behalf of the CD. Section 32A, which provides criminal immunity only for "offences committed prior to the commencement of CIRP," was read as a textual indicator that IBC's immunity provisions are temporally anchored to pre-CIRP conduct.
Pillar 4 — Constitutional and Public Policy Constraints
The Court ventured into constitutional territory, advancing two additional arguments. First, on the public policy plane, it relied on Amrit Banaspati Co. Ltd.- 1992-VIL-04-SC to hold that extending clean slate to indirect taxes collected by the CD from its customers but not remitted to the exchequer would violate public policy. It would lead to unjust enrichment in the hands of SRA under the guise of insolvency immunity. Second, the Court, upon examining the 101st Constitutional Amendment introducing Article 246A held that this constitutional architecture limits the reach of the IBC for the State.
4. A critical appraisal of the judgments
The judgments are structural well founded, in the sense that the post CIRP dues are carved out from clean slate both on sound logic and legislative framework. However, the judgments leave open a practical vacuum. First, if post-CIRP tax dues are IRPC payable in full by the SRA, and the resolution plan did not account for them, the SRA effectively inherits a liability it did not price into its bid. This creates a distorted incentive structure, the resolution applicants who conducted thorough due diligence and discovered potential post-CIRP tax exposures would bid lower or not at all, undermining the IBC's value-maximization objective. Second, the disposition risks undermining the IBC's time-bound resolution objective. If post-CIRP tax dues survive plan approval as enforceable IRPC obligations, assessable years after implementation, the SRA faces indeterminate fiscal exposure long after taking over the CD. This uncertainty may deter resolution applicants, prolong negotiations, inflate risk premiums built into bids, and ultimately reduce the recoveries available to creditors, cutting against the IBC's core efficiency rationale
5. Aftermath and open questions
5.1 The IRPC Classification: Full Payment with No Haircut
If post-CIRP tax dues are IRPC, the consequence is significant and one-directional: they must be paid in full and in priority under Section 30(2)(a), ahead of all creditor distributions. They are not subject to CoC negotiation, the CoC has commercial wisdom and SRAs must therefore treat the full quantum of post-CIRP fiscal dues as a mandatory first-call on available funds, not a liability amenable to compromise. This needs to be factored explicitly into bid structuring.
5.2 Limitation for assessment
A practical concern of considerable importance. Under the CGST Act, as per Section 73/ 74/ 74A, the assessments must be initiated/ concluded within a specified period. If the CIRP extended the period during which assessment proceedings could not be initiated, a significant question arises about whether the statutory limitation period was suspended. Section 60 (6) of the IBC, which excludes the moratorium period from the computation of limitation, provides a partial answer, but its application to tax assessments as distinct from recovery proceedings has not been judicially settled. It will likely become a battleground for years to come.
5.3. who bears the liability for the RP's failure
When the RP fails to discharge post-CIRP tax dues, the SRA effectively inherits an undisclosed liability. The RP's failure to file returns and pay taxes during CIRP constitutes a breach of the statutory duty under Section 17 (2) (e) and the IBBI Code of Conduct. Whether the SRA has an actionable claim against the RP for indemnification in respect of such liabilities is an unresolved question that merits both legislative attention and legislative and administrative guidance.
5.4 The ITC set-off
The Court in Aqua Terra explicitly construed the situation of set off i.e. even if clean slate does not extinguish post-CIRP tax dues, can the tax authority set off those dues against ITC balances available in the electronic credit ledger including ITC accumulated from the pre-CIRP period.
The question has two distinct dimensions. First, from the IBC's perspective, pre-CIRP ITC balances constitute an asset of the CD's estate as on the insolvency commencement date. The RP's duty is to conserve and maximise estate assets. Compulsorily depleting that asset by mandatory set-off against post-CIRP dues would effectively give the tax authority a preference over other creditors inconsistent with the IBC's waterfall. Second, from the GST statute's perspective, the electronic credit ledger under Section 49 of the CGST Act permits free utilisation of available ITC against output tax liability no separate act of appropriation is required, and the mechanism appears automatic.
5.5. State’s authority to question legitimacy of ITC availed during pre-CIRP and post CIRP periods
The Court in Aqua Terra further flags that ITC is a statutory concession citing previous precedents and that extending ITC without scrutiny of eligibility may be impermissible. This concern is legitimate, the pre-CIRP credit ledger may contain ITC from ineligible sources, reversed credits, or credits claimed on transactions with non-compliant suppliers under Section 16 (2) (c). While the Court in the extant facts resorted to ITC as concession theory, but in its deepest roots the question is extremely vexed. This because the other side of ITC is the payment of tax by the supplier, therefore on theory of moving forward, the government can always catch the supplier, and concede the ITC to the recipient-CD, considering the grand scheme of things.
6. Conclusion and way forward
The Madras High Court's judgments in P Dot G and Aqua Terra establish an important and largely correct boundary on the clean slate doctrine, it is not an instrument of fiscal immunity for obligations incurred during the CIRP itself. The structural reasoning that post-CIRP tax dues are outside the claims pool aligns with the IBC's own internal architecture. However, the unresolved questions, particularly the ITC set-off dilemma and others open a Pandora’s box. The pending CIRP cases should clearly be aligned with the ratio of these judgments so that all the stakeholders can be certain of the conclusion of the CIRP. And finally, the judgments also raise the bar for tax authorities to timely conclude tax assessments.
